Switching charging method

If the battery pack was previously charged using the fuse box method, follow these steps to unlock it and switch to the cigarette lighter charging method:

1. Connect the cable according to the “Connecting to the vehicle cigarette lighter” procedure.
2. Turn on the battery pack and start the vehicle’s engine.
3. Pull out the charging connector from the cigarette lighter socket, wait approximately 10 seconds, then reinsert it into the socket for 5 seconds. Repeat this pull out-and-insert sequence 3 times.
4. Once successfully unlocked, insert the charging cable into the cigarette lighter socket again. After an approximate 20-second delay, the battery pack will begin charging, and the indicator light will show the charging status, indicating the successful unlocking.

If the battery pack was previously charged through the cigarette lighter socket, no unlocking procedure is needed to switch to the fuse box charging method.
